CVE-2026-74465

The CVE-2026-74465 entry describes a potential use-after-free in Linux kernel/Open vSwitch meter handling: attach_meter() may briefly expose a newly created meter and later free it on failure via ovs_meter_cmd_set(), risking UAF if RC reader/window timing allows access. The fix (per the reports) ...
